To all whom it may concern:

' Be it known that I, CHARLES D. JENKINS, a citizen of the UnitedStates, residing at Boston, in the county of Suffolk and State ofMassachusetts, have invented Certain new and useful Improvements inMachines for Extracting Liquids from Various Materials, of which thefollowing is a specification.

My invention relates to improvements in machines for extracting orremoving liquids from semi-solid materials, and more especially to amachine for removing water from peat. The object of my invention is toprovide an improved machine of the character indicated, and it consistsof a machine of this kind embodying the peculiar features ofconstruction and mode of operation set forth in the followingdescription and particularly pointed out and defined in the claim at theclose thereof.

In the accompanying drawings:

Figure 1 is a central vertical sectional view of a machine for removingwater from peat and the like, embodying my invention.

Fig. 2 is a section on line 2-2 of Fig. 1.

Having reference to the drawing 1 is a base-plate from which uprights 2project upwardly to support a top-plate 1 between which and thebase-plate 1 two material compressing members 3 and 4 are located, themember 3 being herein shown as a wheel fixed to a shaft 5 journaled inbearings on base-plate 1 and top-plate 1 while the memher 4 is shown asa ring encircling the wheel 3, and held eccentrically with relationthereto by rollers 6 mounted upon shafts 7, journaled at their ends inbearings on base-plate 1 and top-plate 1'.

The wheel 3 consists of a rim 8 made with pockets 9 within which arearranged blocks of wood 10, whose grain isdisposed radially. The innerends of the pockets 9 have openings 11 communicating with the spaceinclosed by the rim 8 and this space registers with an opening 12 formedin the base-plate 1.

The rim 8 is connected with the hub 14 of wheel 1 by a plurality ofspokes 13.

The ring 4 comprises three annular flan ges 15, 16 and 17, connected bycross-bars 18, and the inner portion of the spac s between the bars 18constitute pockets within which are seated blocks of wood 19 which alsohave their grain arranged radially. The ring MACHINE Eon. EXTRACTINGLIQUIDS FROM VARIOUS MATERIALS.

4 is loose between base-plate 1 and top-plate 1, and is free to rotatearound wheel 1.

The eccentricity of the ring 4 provides a crescent-shaped chamber 20,and a feed pipe 21 fastened to the top-plate 1, commu-- nicates atitslower end with this crescentsh'aped chamber near the middle thereof,said pipe having a segmental extension 22, extending downward intochamber 20 to the top of base-plate 1, which serves as a partition todivide chamber 20 into two separate parts. Within the feed pipe 21 isarranged a screw 23 fixed to or formed on a shaft 24 journaled at itsupper end in a bearing on pipe 21 and at its lower end in a bearing onbase-plate 1. The upper end of feed pipe 21 communicates with a hopper25 into which the wet peat that is to be 0p- -erated upon, is dumped,and this peat is fed downward by screw 23 continuously, the screw shaft24 being provided at its lower end with a gear 26, driven through anidler 27, by a gear 28, fixed to the lower end of shaft 5.

' The upper end of shaft 5 has a bevel gear 29 fixed to it that iscontinuously driven by bevel pinion 30 fast on the main drive shaft 31of the machine.

The wheel 1 is driven in the direction of the arrow, Fig. 2, and thematerial fed into chamber 20, by the screw 23, is propelled by saidwheel toward the point of coincidence of the periphery of wheel 1 withthe inner periphery of ring 4. the engagement of the material with saidring causing the latter to rotate on its axis or center with the wheel 1and the material. Thus the material is very gradually compressed as itapproaches the point of coincidence or closest approach between wheel 1and ring 4. and the material thus compressed is carried past said point,lodged in the curved recesses 32, provided upon the outer sides of theblocks of wood 10. After the material has been compressed it passes intothe other side of chamber 20 and falls by gravity through an outlet 33,provided in base plate 1.

The wood from which the blocks 10 and 19 are made should be as porous oropengrained as is available, in order to secure the best results, and asstated, these blocks are cut and arranged so that their grain isdisposed radially with relation to the axis of the member of which theyform a part.

During the passage of the material toward and past the point ofcoincidence or nearest approach between wheel 1 and ring l the watercontained thereinis forced radially through the pores or grain of thewood blocks 10 and 19, the water passing through the blocks 10discharging through the out let 12 in base plate 1, while the waterforced through the wood blocks 19 flows down upon the outside of themachine. I have found that blocks made from chestnut, ash or birch woodgive excellent results.

The machine above described is very simple in construction, directacting and efficient in operation, but I do not desire to Copies of thispatent may be obtained for five cents each, by addressing theCommissioner of Batentslimit the features of my invention to a machineof the type herein shown.

What I claim is A machine of thecharacter described comprising a memberhaving a solid material engaging wall composed of wood arranged with itsgrain perpendicular to the material engaging face of said wall, andmeans for pressing the material against said wall so as to force theliquid through the grain of the wood. I

In testimony whereof I have aflixed my signature.
